Hi Sara - very nice first spotting! It's great that you posted the second photo separately. Could you remove it from this spotting now? Welcome to Project Noah!
You are welcome and thank you for joining the Mission Caterpillars and Larvae of the Southwest United States http://www.projectnoah.org/missions/1142...
Your second green caterpillar, the green one with a horn on the tail, is the second suggestion. Sphinx moth caterpillars usually have a horn.
Second green caterpillar is not the same. Try posting that unknown caterpillars separately so we can find them and try to help. Great photos thanks.
